Problems solved by technology

[0012] The synergistic combination of pesticides is an effective measure to expand the control spectrum and improve the control effect. Lepidoptera pests, such as cabbage caterpillars, cotton bollworms, aphids, beet armyworms, and rice stem borers, have gradually increased their resistance at present. The effect on pest control is gradually declining, and the compounding of pesticides can significantly improve the efficacy and delay the generation of pest resistance, but so far no insecticidal composition related to pyrimaben and lambda-cyhalothrin has been found

Embodiment 1

[0025] Weigh 4 grams of pyrimaben, 1 gram of lambda-cyhalothrin, 4 grams of calcium dodecylbenzenesulfonate, 3 grams of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total weight of 100 grams. The above raw materials are put into a mixing tank according to the conventional method for preparing EC and mixed to form a preparation of 5% pyrimaben-effective-cyhalothrin EC.

[0026] Indoor synergistic bioassay was carried out, the resistant diamondback moth was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the co-toxicity coefficient was calculated according to the Sun Yunpei method with the LC50 value:

Embodiment 2

[0032] Weigh 4 grams of pyrimaben, 2 grams of beta-cyhalothrin, 3 grams of phenylethylphenol polyoxyethylene ether phosphate, polyoxyethylene polyoxypropylene block compounds such as agricultural milk 33 # 2 grams, 1 gram of alkylphenol polyoxyethylene ether, 13 grams of xylene, add water to a total weight of 100 grams (weight ratio). Put the above raw materials into a mixing tank according to the conventional method for preparing water emulsion, and mix at high speed to form a water emulsion preparation of 6% pyrimaben-beta-cyhalothrin water emulsion.

Embodiment 3

[0034] Weigh 2 grams of pyrimid, 2 grams of beta-cyhalothrin, 6 grams of calcium dodecylbenzenesulfonate, 3 grams of phenylethylphenol polyoxyethylene ether phosphate, polyoxyethylene polyoxypropylene block Nongru 33 # 2 grams, 1 gram of alkylphenol polyoxyethylene ether, 10 grams of cyclohexanone, add water to a total weight of 100 grams. Put the above raw materials into a mixing tank according to the conventional method for preparing microemulsions, and mix them to form a microemulsion preparation of 4% pyrimaben-beta-cyhalothrin microemulsion.

Abstract

A synergistic composite insecticide for preventing and treating cabbage caterpillar and rice borer contains two primary active components including high-effect cyfluthrin, assistant and excipient.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with pyrimaben and lambda-cyhalothrin as main active ingredients and its application. Background technique [0002] At present, pyrimaben (test code: NA83, common name: fluacrypyrim, trade name: Titaron) is the first methoxyacrylate acaricide developed by BASF and Nippon Soda. Pyrimiden was randomly synthesized and optimized on the basis of methoxyacrylate fungicides. The chemical name of pyrimidin is methyl(E)-2-{a-[2-isopropoxy-6-(trifluoromethyl)pyrimidin-4-yloxy]-o-tolyl}-3- Methyl methoxyacrylate. [0003] Pyrimiden is a mitochondrial respiration inhibitor that inhibits mitochondrial respiration by electron transfer between cytochrome b and c1. Mitochondria outside the nucleus mainly provide energy (ATP) for cells through respiration. If mitochondrial respiration is blocked and ATP cannot be produced, cells will die. [0004] ...
